The composition of CaO-SiO 2 -MgO-Al 2 O 3 -CaF 2  slag was designed by thermodynamic calculation of [Al]-[O] equilibrium of FeNi-based expansion alloy. On this basis, the deoxidation and inclusion evolution in the process of slagging and smelting FeNi-based expansion alloy in the medium frequency induction furnace were investigated. The results show that the oxygen content in the alloy melt is mainly controlled by the [Fe]-[O] equilibrium, and the change trend of the equilibrium oxygen content calculated by [Fe]-[O] equilibrium is consistent with the actual oxygen content. The total oxygen content of the final ingot is 45 ppm. After Al deoxidation in the melting process, the inclusions in the alloy are transformed into composite oxide inclusions rich in Al 2 O 3  and MgO. After final deoxidation with Si-Ca alloy, the contents of Al 2 O 3  and MgO in the inclusions decreased significantly, while the CaO content increased. And there are mainly CaO-SiO 2 -MgO-Al 2 O 3  composite oxide inclusions in the ingot.
